Help needed with finishing and laying out a fairly simple MOSFET-based RGB LED driver in the form factor of an Adafruit Feather shield. I'm using the Adafruit Feather M4 Express to prototype and this will be a shield that stacks on top. I already have a working circuit I just need to transfer to PCB in Feather shield form factor and basic review.
The Eagle schematic is mostly finished and I have begun board layout, but I could use help routing and laying out the board. The base PWM clock is quite high (40+ MHz) so I would like someone who has experience with high frequency digital signals to assist with trace width, optimal layout, bypass capacitor value and placement, etc.
I believe this job could be a fairly quick turn around: help finishing the circuit, and layout & routing.
I am using Seeed and Seeed's Open Parts Library with Eagle so experience with this is desirable ([login to view URL]).

Update: I have added design files and a requirements document to the project so you can better see what the job entails. Please look at these documents to get more clarity on the project.
